`The apparatus according to this invention comprises a cylindrical aerating receptacle l 'which is closed at the bottom and has an inlet 2 at a suitable height from the saidy boo. toniihrough which the liquid is admitted into the said aerating apparatus. `The aeratingreeeptaeleis provided with anupwardly extending Vcylindrical part 3 which constitutes a housing for parts hereinafter de scribed andthe said receptacle is supported stitutes a closure for the bottom of the said receptacle. The aerating `receptacle `1 has a piston-like body reciprocal therein consisting of a plunger 5 which is smaller in diameter than the internal diameter of the part'kof the receptacle in which the said plunger 'ree ciprocates, the space between being covered by a flexible valve 6 opening downwards as described in the specification of the British Letters Patent No. `2297 33. Extending up` `y wardly from the plunger 5 is a stem 7 having a head, or flange, 8'whicl1 lconsti'tutesa. rclosure for the loweil end of a discharge vessel 9 secured to the said head, or flange, so that it'reci'procates with the said plunger. Extending axially through the plunger 5, stem 7 and head, or flange, 8 is a vpassage -10 through which the aeratedliquidis expelled upon the descent of the 'said plunger, into the discharge vessel 9 from which it passes through an outlet spout 11 into a glass, or other container, placed in yposition to receive it." The dischargevessel A9 is housed 'and guided in the upward extending part 3A of the aerating receptaclejl andthe saidpart' hasta suitably shaped slotV 12 formed therein.

through which'the outletk spout 11 projects. The outlet 13 of the passage 10 is controlled by a combined discharge and' safety valve 111 which is connected to an operating handlever 15fby means such that willv permit 'the said valve to lopen the vsaid outlet when va predetermined pressure is reached within the aerating' receptacle 1 and will causethesald valve toopen' land closej'the s'aid outlet at the proper times. vThis is effected by attaching the valve'la't'o thejlowerf end of aspring 16 the upperend of which is secured, throughja guide rod y17, to 'n inwardly-projecting piece'18`for1ne`d on aiaclr-bar 19' with which engages ai tooth pinion 20j secured` to la shaft 21 rotatably mounted in bearingbracl'rets22 securedto, or formed in one with. the upper end of thedischarge vessel 9, to whi'ehfshaft theoperating hand-lever15V isvsecured. i Y p Presmnls the' "rillingen 5 t0 be beating upon thefflat bottom of the aeratingvrelceptacleY 1 asshewn in Figure 2 and 1 andthat the saidreceptacle hasbeen'charged with lliquidhto vbe 'aerated the operationfof'the apparatus is as follows'z-e-'e AUponj'turning the y v hand-lever 1 5 in the direction fof the arrow, shewn in `Figure'2, the tooth pinion 2.0 moves. the leek-@19 devudlyhei'- bycaiisiiig the 'combineddischarge and valve 14H10I be moved towards' its se'atiiiitil further "downward v'movement the said rack-bar is prevented' byfapfa'rt 23 thereef eiigagingy an ,abutment constituted/hva `lever 24 (hereinafter 'more' particularly described) normallyr held stationary` vbythe action 'ofa spring 25. the rack-bar 19 cannotfnew be moved downwardly, further 'movement ,of the yhand-lever 15 rin the. saine 'direction lcauses the tooth pinion 2O to abtas'alever,

To assist in overcoming the aforesaid suction effect th'e flexible valve may have Aholes 26 through it. VVhenby the movement of the handlever 15 the plunger 5 has been raised from the flat bottom l of the aerating receptacle 1 and the outlet 13 of the passage 10 has been moved up against the combined discharge and 4safety valve 14, thereby stoppingfurther ingress of -air through the said passage 1() to ythe underside of lthe lplunger 5, further movement ofthe said hand-lever, in the 'same direction, will thenl simultaneously compress the spring 16 and lift the discharge vessel 9 and all parts connected thereto including the combined discharge and safety valve 14 and plunger v5 until the said yplunger is seated against'an internal flange, or constriction, 27 at the upper end of the said aerating receptacle. Upon further movement of tl'iei'hand-lever 15, in the same direction, gas under pressure is admitted tothe interior of the aerating receptacle 1. as being :effected as follows:` Adapted to be* screwed, or'pkotherwise attached, to the voutletfofv a'gascontai'ner (not shewn) is a valve-casing28r`having a 'valveechamber 29 within' whichis a valve 30 which controls the'finlet of gas into the said chamber. A tilblilarpiece 31, the ends of which fit gas- Vthightly"into holes formed ink the valve-casing 28 and basepiecev 4, respectively, effects comnuin'catonbetween the'interior of the valveeha'mber29`L and the kinterior of the aerating receptacle'l. |Thev valve 30 slidably'ts witlr in 'the valve-chamber 29and is normally held down'by the before mentioned spring 25 and closes a port, or channel, 32 through which the gasvunder pressure passes into the said vaive-chamber.` :The valve may be providedwithla renewable seating: 33 of hard vulcanitefor. other j suitable material. The lever 24: -`is pivotally mounted in'a forked 'piece lscrewed "onto the upper end of a yr'odu35''slidable through a hole in a plate 36, pivotally supported on brackets 37 secured to, or1 formedin one with. the'upwardly ex- N tending cylindrical part 3. The spring 25,

under compression, surroundsthe rod 35 aindfbearsonv the underside of the plate 36 and thefu'pper side of 'a collar, or enlargement, 38 on the lower end of the said rodand the pressure'of the said spring is transmitted This is shewn llt) lil i `the gas on its under side.

or enlargement, 38 and the lower end of which bears upon the upper side of the said valve. The spring may be compressed by any suitable means, 4for example, this may be elfecterfl las shewu in Figure l by rods 4l4 screwed at their lower ends into a flange i2 formed on the valve-casing 28 the upper ends of the said rods being screw-threaded and passed through holes in the plate 3G and having nuts 43 screwed thereon so that by screwing down thejsaid nutsthe said spring can be compressed sufficiently to, transmit,

through the rods 35 and 39, such pressure on the top of the valve that `it prevents the said (valve being raised by the pressure of rThe strength of the. spring 25 `is also such that it prevents movement of the lever 24 when it constitutes the abutment for the rack-bar 19. while the plunger is being raised,`as aforesaid, vbut when the plunger `5 is in contact with the internal flange," or constriction, further movement of the hand-lever 15 will, through the said rack-bar, cause the said lever to turn on its fulcrum,f constituted by a post 4a interposedubetween the said lever and the plate 36, and raise the rod in opposition to the action of the said spring, thereby relieving the rod 89 of pressure so `that the pressure of the gas will now act to force the valve 30 and the said rod 39 upwardly and consequently the vgas will pass through the port; or channel, 32 into the valve-chamber 29 and from thence through the' tubular piece 31 into the receptacle l and aerate the liquid therein# The position of the parts will now be that shewn in Figure 3. Any suitable means may be provided for preventing leakage of gas from the aforesaid valvular device. This is shewn as being effected by a suitably shapedtubular piece of rubber 4-5 fitted `onto'a part of reduced diameter of the rod 39 the said piece of rubber having a flange, or collar, which closely its against a flangedbush, or collana@ through which the valve rod passes out of the valve-cha1nber 29. Any gas leaking past the valve 3() will act to force the rubber piece't more tightly against the bush, or collar, 46. [is a precaution against leakage of gas between the hanged bush` or collar, 4,6 and the wall of the valvechamber 29, the Piange of the said bush, or collar, fits within7 and bears upon the bottom of, an orifice of larger diameter than that of the 'valve-chamber 29 of which it is au extension. A rubber ring, or other suitable packing` ll? surrounds that part of the bush or collar, 46 extending above the iiange.v4 and this -rubber ring, or other packing, is pressed tightly against the wall of the orilice by another collar Sfsuperposed upon the said rubber ring, or other packing, i7

ward moven the said collar 48 being pressed downwardly by agland't) (through which theerod 39 passes) screwed :into the upper end of the valve-casing. rlhe gas in its passage from the gas container to the port,V or channel,

preferably passes through a'linely perfo,-

i'ated tube 50 screwed into a hole beneath the said -port,f or channel. The pressure of the gas `adn'iitted into the aerating receptacle l artsiupon the flexible valve 6 on the undersside `of the plunger 5 and ensuresa gas-tight closure `at the top of the said receptacle.

TWhen the pressure in the aerating` receptacle l exceeds a predetermined amount the spring 1G? of the combined discharge and safety valve 11i will yield sufliciently torallow the.

ercess pressure to escape. t

`Upon turning the hand-.lever 15 inst-he reverse direction the raclrebar ,19. is. raised, bythe tooth pinion 20, thereby' freeing the lever '24 so that by the action of the spring 25 the valve 30 is again forced downwardiy`` and closes the port or channel, 32. The upmits the `spring l@ of the @combined -dis-` charge and safety valve 14; to 'extend sufficiently to permit of the escape' of any gas that may not have been absorbed by the liquid and further upward' movement Vof the said rack-bar will lift thersaid valve oil its seating to permit ofthe discharge'of the aerated liquid which discharge isefi'ected by applying a downwardpressure to the plunger 5 throughthe hand-lever l5 whereby the liquid beneath the plunger is forced by the rdescent of thesaid plunger throughthe passage l0 into the discharge vessel 9 above from which it passes through the outlet spout l1 into` glass, o-r other container, placed in position to receive it.

i The greater portion of the apparatus rmay be enclosed in a wooden box 5l, preferably as :ihewm the lid, or cover, 52 of which is made in parts hinged theretoso that access can be had to the parts within the said box, rlhe ylever 2e .and the plate 3G supporting the gas valve-casing 28 project through an opening in the adjacent side of the box 5l so ,that the said valve-casing and parts associate therewith are on the outside of the said box.'1 the tubular piece Bl conducting the gas tothe aerating receptacle 1l passii'ig through a hole in the said side of the born The aforesaid parts may be enclosed by a metal cover` or guarih as shewn, secured by bolts 5a, preferably provided with winged heads, which pass through the said cover, a piece secured thereto and bearing on the valve-casing 287V then through holes in the side of the boX 5l and screw into the base-piece rlhe bolts 54 uct to secure the base-piece 45 the tubular piece 8l and the valve-casing 28 together in such manner that a gasitight connection of the said parts is ensured, 'and said t of theiraclr-bar 19 also per-L lll@ - other required purpose. lThe outlet pipe ll from the discharge vessel 9 projects through another aperture in the aforesaid side of the box 51, the said. aperture being of a length such that it will permit of. the ascendingand descending` movements ofthe said pipe. A metal cover, or guard, A57 may, if desired, be secured over the outwardly projectingV ends of the pipes ll and 86. The upper part of the bearingA brackets 22 carrying the shaft 2l with the tooth pinion 2O thereon and the upper part of the rack-bar V 19 iro'ect throue'h ana ierture in the lid of the boX 5l and these parte are preferably enclosed, as shewn byv a metal cover 58 'Y (which may as shewn be made in two parts) secured to the said lid. The ends of the shaft 2l to which the operating hand-lever l5 is secured project through slots 59 in the cover -581 of such length that they will permit of the ascending and deseending movements of the said'shaft.

Thev upper part of the rack-bar 19 is guided and maintained in engagement with the tooth pinion 20 by a straddle-piece 60 the leg portions of which are secured to the bearing brackets 22.,

It desired, a counting device may be provided to indicate the number of operations, or the amount ofliquid treated and drawn off, the said device being operated by any suitable moving' part of the apparatus. This is'shevn, by way of'example, as being effected bysecuring a counting device Gl to the cover-.58, the said counting device having cranked operating arni 62 which engages with a cam-shaped slot in a plate securedv to the straddle-piece 6() so that at each v`upvvardfor downward movement of the bearing brackets 22 the said counter will be operated. A suitable aperture 65 is formed in the cover 5B-through which 'the recording numerals of the counting device can be seen.

The liquid to be aerated may be supplied to the aerating receptacle l from an inverted bottle, or inverted bottles, GG- adapted to maintain the liquid in the said receptz'icle at a predetermined level. The inverted bottles 66 are shewn supported in funnel-shaped holders 67 which project downv.'ardly through holes formed in the lid 52 towards the opposite ends thereof. The lower end of each of the holders G7 also projects iiuto 'the upper end of a tubular piece G8 (preferably provided with a strainer 69, as shewn in Figure Ll) in communication with al closed shallow tank 7() the bottoni of the interior of the bonr ljinto which tank a hollow eX tension 7l of the Abase-plate 4 projects and constitutes a continuation of the inlet 2 of the aerating receptacle l, so that the liquid to be aerated passes from the bottles 66 into the tubular pieces G8, from thence into the closed shallow tank 70, then up the extension 7l and inlet 2 into the said aerating receptacle where it rises to a height level with the outlet end of the 'said inverted bottles.-

:lf desired the apparatus may be provided with a medium (such for example' as ice) for cooling the liquid to be aerated. For this purpose the interior of the box 5l is preferably lined with metal 72' and a suitable amount of broken ice is introduced therein which will act to maintain the closed tank 70, and other parts of the apparatus, cool. The tank is provided with feet 73 so that the said tank will in normalconditions be submerged in cold water produced from the melting ice and the liquid in the tank will thereby be etficiently cooled. IBattles, such as 7e, may be provided in the tank 70 so that the liquid therein will be constrained to Vtlow in a eircuitous path from the inlet to the outlet thereof. The box 5l may be provided with any suitable water outlet, such for exainjile the outlet 7 5 through which the water can pass when it has reached a predetermined height above the closed tank T0.. if; suitably shaped guard 76 may be secured to the upwardly extending cylindrical part 3 which is adapted to prevent ice obstrueting the downward movement of the outlet spout ll through which the aerated liquid is discharged. c

lf desired the apparatus may be provided with means for delivering a iiavouring liquid (hereinafter referred to as the flavouringl syrup) into the glass, or ther container, into which the discharged aerated liquid is to be, or has been, received. rl`his vmay be effected by providing a' tank, or tanks, 78 within the box 5l for containing the'fiavouring syrup which may be supplied from an inverted bottle, or bottles, 79 supported in a funnel-shaped holder, or holders, 80, projecting through a hole, or holes, in the lid 52 of the said box, the height of the outlet of 'the said bottle, or bottles, determining the height of the syrup in the said tank, or tanks, .in the manner well known. rlhe tank, or tanks, .78 is, or are, preferably removably carried by a bracket 8l secured at its rear part to the interior of the box 5l and having at its torwardj'iart a projection 82 which bears on a shoulder 83 formed on the cylindrical extension 3 of the aerating receptacle l. Movable within 'the tank, or each of 'the tanks, 78 is a ladle Si by means of which a predetermined quantity of the syrup can be conveyed therefrom to a hopper 85' secured within the box l in proximity to the ton ward part of the said tank, or tanks, from which hopper the syrup then flows through a pipe 86 into the glass, or other container,

into which the aerated liquid has been charged or into which the said liquid to be discharged.. The ladle 841- is pivotally caw ried by an oscillatory trame 87 pivotally mounted on brackets 88 secured to the underside oil the lid 52 ot' the box 5l at, or towards, the rear part thereof, which trame can be oscillated as required by a handoperable lever 89 the forward end ont which projects through an opening in the front side ot the said box and the rear end ot the said lever being pivotally connected to a lever 90 secured to, or formedin one with, the said trame. The ladle 8% when in its` normal position is above Ythe level. of the syrup in the tank 78 and bears at its torward top edge against the rim o' the or- Ward side of the said tank as shown in Figure 3. By pushing the hand-lever 89 inwardly the frame 87 is turned on its bearings, thereby lowering the ladle into the tank to the limit of the inward movement of the said handdever as shown in Figure 2 whereupon, by pulling the said hand-lever out to its original position, the said ladle is raised, and in consequence turns on its pivot and discharges its contents into the hopper 85. It desired a stop'9l may be provided on a transverse member 92 ot the trame 87 which is adapted to limit the turning movement of the ladle 84 on the `said trame.

A guard, or shield, 93 may, if desired, be secured to the lidl52 ot the box 5l to protect the bottle, or bottles, 79 containing the syrup and this guard, or shield, may be adapted to constitute an abutment to limit the rearward movement ot the hand-operating lever l5.V
